In brief

Galaxy Research tracked six Bitcoin wallets dormant since 2011, 2012, and 2014 moving coins over a 10-day stretch this month, worth a combined $40.15 million.

Two of the six carry "Salomon Client Dusted" tags tied to Noah Doe, the pseudonymous plaintiff suing to claim 39,069 dormant Bitcoin addresses in New York court.

The oldest coins in the batch were bought for pocket change in mid-2011 and are up more than 800,000% on the initial purchase.

Somewhere out there, six people may have just remembered they own Bitcoin, or cracked open an old hard drive, or got their prayers heard and recovered an old key.It isn’t clear what the case may be, but Galaxy Research has been keeping count: Six Bitcoin wallets dormant since 2011, 2012, and 2014 moved a combined 553.59 BTC between Aug. 16 and Aug. 26, worth a combined $40.15 million.Myriad: Bitcoin next price move?

Galaxy reported 212 BTC moving out of a wallet dormant since Aug. 10, 2012—14.0 years.
